WINKEL linear axles of the DLE series are value-analytically designed and manufactured systems for load capacities from 80 kg up to 4.000 kg in steel profile construction with recirculating ball bearing guides. The precise DLE linear axis or multi-axis system, suitable for high load capacities, reaches speeds of up to 5 m/s. The motors for load movement are available as AC or servo versions in combination with low-backlash gearboxes. The D in DLE stands for Dynamic Linear Axis Unit.
WINKEL linear axles of the DLE High Dynamic series are used for loading and unloading of machine tools and industrial production plants, palletising technology and in automotive and aircraft construction.
WINKEL linear axles of the SLE series is a value-analytically designed and manufactured multi-axis system for load capacities up to 4.000 kg and impresses with its insensitivity to dirt and robustness. The SLE linear axis is low-maintenance and suitable for multi-shift operation. Motors are available in AC or servo versions in combination with low-backlash gears. By the way, the S in SLE stands for steel, linear axis unit.
Linear axles of the SLE Heavy Duty series have a modular steel profile design and find applications in dust and dirt in the automotive industry, palletising technology, steel and building materials industry and timber industry.
WINKEL linear axles series PLE is a value-analytically designed and manufactured multi-axis system for load capacities up to 100 kg. The PLE linear axis is very quiet and robust for semi-precise applications. The PLE linear axis requires little maintenance and is suitable for multi-shift operation. By the way, the P stands for Polyamide, linear axis unit.
Linear axis of the PLE High Dynamic series are particularly in demand in applications in the packaging and automotive industries.
WINKEL robot axles of the RLE series are value-analytically designed and manufactured linear systems for loads up to 10,000 kg and can be used in combination with 6-axis robots as a modern 7th linear axis. WINKEL manufactures RLE robot axles ready for connection with matching robot base, reduction gear and central lubrication. Optionally, the matching robot base as well as an elevation for the axis are also offered.
RLE robot axles are low-maintenance and suitable for multi-shift operation.
RLE robot axles are characterised by high-precision positioning through hardened recirculating ball or flat guides and rigid steel profile construction with low-backlash gearing.
RLE robot axles are suitable for all robot makes and applications, e.g. as handling robots in warehouse logistics, machine tool linking or painting or welding robots, and offer great flexibility in workpiece handling. RLE robot axles can be used both floor-guided as a floor axis, as a vertical robot axis or as a gantry solution.
The WINKEL ReadyTrack floor axles type RTP (Ready Track Precision) or RTS (Ready Track Speed) are value-analytically designed and manufactured floor axles for loads up to 5.000 kg. Both variants are manufactured with WINKEL precision profiles. For the rollers, a distinction can be made between a WINKEL polyamide Bearings (RTP) or a WINKEL steel Bearings (RTS). Due to the design, a wide variety of applications can be implemented with the ReadyTrack series. Motors are available in AC or servo versions in combination with low-backlash gearboxes.
Floor axles of the ReadyTrack series find applications as superstructures for lifting systems, lifting systems with transverse lift, telescopic forks with eccentric lift table or chain and roller conveyors in various environmental conditions both in dust and dirt in the automotive industry, palletising technology, steel and building materials industry and timber industry.
Linear axes with high precision and rigidity are required for moving a robot. This is achieved by using ball rail guides or flat guides. In principle, a ball rail guide is recommended for achieving high precision. This is achieved, among other things, due to the smaller clearance between the guideway and the carriages with internal rows of balls.
Linear guides that have combined bearings in combination with guide profiles are suitable for the use in foundries. The advantage is the durability and robustness of this system. The ball bearings are protected against dust, dirt wipers are installed in front of the combined bearing and the running surface of the combined bearing is very durable.
For loading and unloading of machine tools with a linear axes, high precision is required in most cases. Therefor a LM guide is recommended to achieving high precision. This is resulting, due to the smaller clearance between the guide rail and the carriages with internal ball rows.
The 7th axisextends the application range of a 6-axis robot, a 6-axis robot is comparable to the movements of a human arm. The 7th axis gives the robot the ability to move its "own position". This traversing axis is then called the 7th axis.
In dirty areas of application of linear axes, especially in foundries and in the wood industry with high ambient dust, the rolling bearings of the linear axes can become dirty and damaged. With WINKEL steel bearings, SLE linear axes can be used in these environments with dust and dirt due to their insensitivity. The WINKEL design consisting of steel profile and steel bearings with wiper prevent wear and ensure smooth operation in multi-shift operation. For use in dust and dirt, we recommend the WINKEL SLE linear axes.
In the case of low ceiling heights or other interfering contours, the use of a classic linear axis, for the vertical movement, is often not possible due to the overall length resulting from its design. This is due to the fact that the axis has a base unit which has to be moved during the movement and thus the actual construction height is exceeded. In order to solve the problem, it is possible to design the vertical axis as a telescopic axis. With this solution, the vertical movement is implemented by an axis consisting of segments that can be moved into each other. This reduces the overall length and the basic unit does not have to be moved.
With linear axes a maximum speed of up to 5 m/s (18 km/h) is possible, depending on the weight of the load to be moved and the guide system, i.e. LM guiding or WINKEL linear guides.
WINKEL manufactures linear axis with a max. speed of 3 m/s (3,6 km/h) that can move heavy loads up to 10 tons. Loads up to approx. 400kg can be moved with a speed of 5 m/s (18 km/h) in combination with LM guiding.
The rule "the more weight or load to be moved, the lower maximum speed of linear axis".
With WINKEL linear axes loads up to 10 t can be moved precisely, the linear axes are manufactured in steel profile construction with low backlash gear and must be equipped by hardened recirculating ball bearing guides or flat guideways and thus achieve a high rigidity. For loads up to 10 t, RLE robot axes are suitable as 7th linear axis in combination with 6-axis robot. For loads up to 4,000 kg, SLE linear axes in heavy duty design are suitable for semi-precise applications.
Achieving high precision in a linear axis depends to a large extent on the correct selection of the guide system. In principle, a ball rail guide is recommended for achieving a high precision axis. This is achieved, among other things, due to the smaller clearance between the guideway and the carriages with internal rows of balls.
Sufficient maintenance is essential for the reliable functioning of linear axes. Insufficient maintenance of linear axes increases wear and considerably shortens the service life. To ensure correct maintenance of the linear axis, the maintenance plan should be followed. This is part of the documentation. If this is not available, it is important and essential that all moving parts are relubricated at regular intervals. Lubrication of the linear axis is intended to ensure a lubricant film between the rolling elements and the track of the guide and drive elements, and also to prevent corrosion of metallic surfaces. A functional test of the safety devices should be carried out before each production start. As a general rule, maintenance and service work on linear axes must be carried out when the machine is switched off and secured.
There is no maximum length for the linear axes. Individual sections can be connected to each other at designated connection points. This means that an almost unlimited number of elements can be strung together. However, individual linear axes or sections should not exceed the total length of 12 meters, as otherwise transport with a standard truck is no longer possible. When transporting by container, the length should not exceed 11 meters. It is also important to note that supports should be provided at the latest every 6 m for elevated linear axes, as this minimizes the deflection of the axis.
